Clay geosynthetic barriers. Determination of water absorption of bentonite not-eligible which need to be completely1 Scope This International Standard specifies a method for determining the water absorption of bentonite. The bentonite component is a part of clay geosynthetic barriers (GBR C). Water absorption depends on the specific surface of the fine particles and the surface activity of the bentonite. The test provides an index value for production control testing of GBR C.
